The Graphics Card I have my mind set on is the EVGA GTX 460 2WIN. Ncix has them listed at $450.98 before taxes and shipping.

I'd wait a month and they will probably come down in price. It performs well but it is cheaper just to put 2 gtx 460's in SLI (if your building a new rig anyways if you have to buy a whole new mobo thats a different story).
